The characteristics of the total phase inductance and the angle gamma for salient pole synchronous machines

Deriving the correct formula for the total phase inductance of the salient pole electric machines shows that this parameter is constant with rotor position, and doesn´t vary as is assumed in many literatures. Using the correct expression for the total phase inductance, the current flux-linkage of the salient pole electric machines can be presented as function of phase inductance L(delta) and the angle gamma. In this paper these parameters are further investigated The influence of the saliency effect and the load angle on these machine parameters is analysed. Also the relation between the total phase inductance and the dq-inductances is derived.
